Hanna Morris · Answer 1

All in all, there are 24 dvds and choosing 3 of them will give us,

24C3 = 2024 ways

2024 ways. If we are to select the dvd as given in the order above, we can use the basic principle of counting such that,

5 x 8 x 11 = 440

Dividing the second number by the first and multiplying by 100% will give us an answer of 21.739%.
